Which phase of mitosis does this statement accurately describe: during this phase, the sister chromatids separate and move toward opposite poles. a. cytokinesis b. prophase c. metaphase d. anaphase

D. Anaphase       Answer b is correct. This is one of the events that occur during anaphase. During anaphase, the cohesin proteins binding the sister chromatids together also break down, and the non-kinetochore spindle fibers lengthen, elongating the cell. Answer a occurs during metaphase, which happens before anaphase.
